horn wont work. fuse is good and horn works when jumped to the battery. do not hear an audible clicking sound that happens when relay is activated

I can drive to about 35 miles per hour but not more ....

What can be the problem , please ?

I have driven about 200 miles like this .... I also noticed that the fuel consumption is very bad ....

Can anyone give any advice ?
